there is only problem about systemd not addressed by this script
is that it does mount /dev which stops getty from starting on tty1
so either make it start on any tty higher than what your host is using
and allow that in your lxc cgroup conf
or mount the $rootfs/dev to a different block dev that way systemd
won't mount /dev
the script below does it nicely in the case you don't have a free
block device. the script create a non persistant mount which you don't
need if you are using lvm

Yes, I think ideally you'd have a single
/var/lib/lxc/fedora-devs
mounted from a single loopback or block device, with each container
having a /var/lib/lxc/fedora-devs/containername directory, populated,
for its dev, bind-mounted in through lxc.mount.entry.
